Answer: lymphatic circulatory; respiratory
Explanation:
The autonomic nervous system controls the internal body functions and responses which are not under the voluntary control. The functions control by the autonomous nervous system are heart rate, body fluid circulation, respiration, urination, sexual arousal and pupillary response.
The lymphatic system is one of the part of the circulatory system, it consists of a network of connected tubes called as lymphatic vessels. These vessels distribute the lymph fluid throughout the body. The lymph fluid consists of white blood cells which provide immunity against the pathogen.
The respiratory system is the system which controls the exchange of gases (Carbon dioxide and oxygen) between the body and the environment.
Both lymphatic circulation and respiration are the two functions controlled by the autonomic nervous system.
Cell membranes are first proposed to be composed of phospholipid bilayers by Singer and G. Nicolson.
<h3>What do you mean by cell membrane ?</h3>
A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The passage of chemicals into and out of the cell is regulated by the cell membrane.
- As a result, the cell membrane has two functions: first, it acts as a barrier to keep the cell's components in and undesirable substances out, and second, it acts as a gate to allow the entry of essential nutrients and the exit of waste products.
